Fluctuations in dc SQUIDs: Quantum Noise Effects, Low Frequency Noise, and Single Electron Trapping
… and noise properties of extremely sensitive dc SQUIDs composed of submicron area tunnel junctions. At high frequencies, the flux resolution is expected to be limited by intrinsic quantum fluctuations, making these devices prime candidates for ideal quantum-limited detectors. The observed …

Experimental determination of the symmetry of the superconducting pairing state in yttrium barium copper oxide
… I present measurements of bimetallic Pb-Au-YBCO dc SQUIDs (Superconducting QUantum Interference Devices) and Josephson junctions that provide an important clue to the origin of the pairing mechanism for high temperature superconductivity in the cuprates. By probing the momentum space anisotropy …

Resistance in Superconducting Epitaxial Niobium Nanowires
… links nor grain boundaries dominate the observed DC resistance at low temperature. The epitaxial films in this study are between 10 and 30 mn thick. While the finished wires range in length from 1 to 10 mum; and in width from 35 to 400 nm. Transport measurements on the nanowires of varying widths …

Focused Ion Beam Fabricated Non-equilibrium Superconducting Devices
… for making high-density SNS junction arrays, dc-SQUIDs, and related devices. A simple model is devised to explain the normal-state resistance and critical current of a junction. The model is based on the geometry of a junction as defined by the FIB instrument and the film deposition. The model …
